The Fuel Injection Pump 294000-0039 (OE part number 8-97306044-9) is a Denso HP3 series core component exclusively engineered for Isuzu 4HJ1 diesel engines, widely powering Isuzu Elf NKR/NHR/NPR series light trucks, commercial vehicles, and off-road machinery. Manufactured with high-strength alloy steel via ultra-precision CNC machining, it meets strict OE standards, featuring a maximum injection pressure of 1600bar and fuel supply accuracy within ±2%. Its advanced common rail system optimizes atomization to match the 4HJ1’s 66–81kW (90–109hp) output and 176–294N·m torque, boosting combustion efficiency by 15%, cutting fuel consumption by 11%, and complying with Euro III emissions. The drop-in design enables plug-and-play installation without modifications, reducing downtime by 50% versus generic alternatives. Undergoing 500+ hours of high-load bench testing, it resists wear and cavitation effectively, extending service life by 25% beyond industry averages, and is backed by a 3-month warranty and global after-sales support.
